Semicircle:
diameter = 6 yd
r = 6/2 = 3 yd
[tex]Area \ of \ semicircle = \dfrac{1}{2}\pi r^{2}\\\\[/tex]
[tex]=\dfrac{1}{2}*3.14*3*3\\\\= 14.13 \ yd^{2}[/tex]
Triangle:
base = b =6 yd
height = h = 4 yd
[tex]Area \ of \ triangle = \dfrac{1}{2}bh\\\\[/tex]

Abby practiced her horn for 3/4 of an hour every day for 12 days?
a) How many hours did she practice in those 12 days?
b) How many minutes did she practiced in those 12 days?
Answers
The time practiced in the 12 days is an illustration of proportions
She practices a total of 9 hours in the 12 daysShe practices a total of 540 minutes in the 12 daysThe total number of hours practicedThe given parameters are:
Days = 12
Proportion = 3/4
So, the number of hours is:
Hours = Days * Proportion
This gives
Hours = 12 *3/4
Hours = 9
Hence, she practices a total of 9 hours in the 12 days
The total minutes practicedThere are 60 minutes in an hour.
So, we have:
Minutes = 9 * 60
Minutes = 540
Hence, she practices a total of 540 minutes in the 12 days

This is timed!!! It is a math equation that I am too lazy to solve.
Answers
Answer: Below
Step-by-step explanation:
Using the information, we can see that they all refer to Elena as a marker for how much they walked, directly or indirectly.
Let's use E for Elena, J for Jada, and L for Lin.
E + 4 = J
E + 6 = L
E = E
We know they all walked a total of 37 miles.
J + L + E = 37
(E + 4) + (E + 6) + E = 37
Simplify.
3E + 10 = 37
3E = 27
E = 9
Using E is 9, we find that:
Elena walked 9 miles
Lin walked 15 miles
Jana walked 13 miles
13 + 15 + 9 = 37, so our answer checks out.
We know that:
[tex]Jada + Elena + Lin = 37 \space\ miles[/tex][tex]Jada = 4 + Elena[/tex][tex]Lin = 2 + Jada[/tex]Finding the distance each walked:[tex]Jada + Elena + Lin = 37 \space\ miles[/tex]Add 4 both sides
=> [tex]Jada + Elena + 4 + Lin = 37 + 4[/tex]=> [tex]Jada + Jada + Lin = 41 \space\ miles[/tex] [tex][Jada = 4 + Elena][/tex]=> [tex]Jada + Jada + Jada + 2 = 41 \space\ miles[/tex] [tex][Lin = Jada + 2][/tex]Changing "Jada + Jada + Jada" to "3(Jada)"
=> [tex]3(Jada) + 2 = 41 \space\ miles[/tex]Subtracting 2 both sides:
=> [tex]3(Jada) = 41 - 2[/tex]=> [tex]3(Jada) = 39 \space\ miles[/tex]Divide 3 both sides:
=> [tex]3(Jada) = 39 \space\ miles[/tex]=> [tex]\frac{3(Jada)}{3} = \frac{39 \space\ miles}{3}[/tex]=> [tex]\bold{Jada} = \bold{13 \space\ miles}[/tex]Substituting the miles Jada walked into the equation "Jada = 4 + Elena"
[tex]Jada = 4 + Elena[/tex]=> [tex]13 = 4 + Elena[/tex]Subtract 4 both sides:
=> [tex]13 - 4 = 4 - 4 + Elena[/tex]=> [tex]\bold{Elena} = \bold{9 \space\ miles}[/tex]Substituting the miles Jada walked into the equation "Lin = 2 + Jada"
=> [tex]Lin = 2 + 13[/tex]=> [tex]\bold{Lin} = \bold{15 \space\ miles}[/tex]
Isabelle plans to line her flower garden with a decorative border. Her flower bed is 60 inches by 78 inches. The border is sold in bundles of 40 ft. How much border will be leftover once Isabelle lines her garden?
Answers
Step-by-step explanation:
I guess, the flower bed is a true rectangle, right ?
so, then, the perimeter of that rectangle is
2×length + 2×width = 2×78 + 2×60 = 156 + 120 = 276 in.
1 ft = 12 in
276 in = 23 ft
she can only buy a bundle of 40 ft.
that means she will have
40 - 23 = 17 ft left.

An outlier is a number that is much larger or smaller than the general populous of numbers. For example, if there was a dot plot with dots clustered at 2, 3, and 5, but there was one or two dots around 10, then 10 would be considered an outlier.I would consider 44 to be an outlier in the number set.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

Erik used 16 centimeters of tape to wrap 2 presents. Then, he used an additional 24 centimeters of tape to wrap another 3 presents. How many centimeters of tape does Erik use to wrap each present?
Answers
Answer:
Erik uses 8 centimeters of tape to wrap each present.
Step-by-step explanation:
16 centimeters can wrap 2 presents.
24 centimeters can wrap 3 presents.
Add both amounts of tape together to find the total amount of tape used. Then add the number of presents wrapped together.
16 + 24 = 40 centimeters
2 + 3 = 5 presents
40/5
In order to find how much tape wraps one present, divide both the top and bottom by the denominator (5)
40/5 = 8 centimeters
5/5 = 1 present
Erik uses 8 centimeters of tape to wrap each present.

Answer: Use the distance formula to find the length of each side, and then add the lengths.
Step-by-step explanation:
To find the perimeter of this quadrilateral with known vertices: Use the distance formula to find the length of each side, and then add the lengths.
What is distance?The distance between two points is the length of the line joining the two points. Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.
Here, we have,
Mathematically, the distance between points on a coordinate plane is given by this formula:
Formula: distance= √(x_2-x_1)²+(y_2-y_1)²
Where:
x and y are the vertices (points) on a coordinate plane.
Therefore, when the distance formula has been used to determine the length of of each side of the quadrilateral. You should then add the lengths of each side together.

Answer: [tex]3\frac{7}{10}[/tex] or [tex]\frac{37}{10}[/tex]
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below. Follow these steps I made for you.
Step 1: Convert [tex]8\frac{4}{5}[/tex] to an improper fraction. Use this rule: [tex]a\frac{b}{c} = \frac{ac + b}{c}[/tex].
[tex]\frac{8 * 5 + 4}{5} - 5\frac{1}{10}[/tex]
Step 2: Simplify 8 × 5 to 40.
[tex]\frac{40 + 4}{5} - 5\frac{1}{10}[/tex]
Step 3: Simplify 40 + 4 to 44.
[tex]\frac{44}{5} - 5\frac{1}{10}[/tex]
Step 4: Convert [tex]5\frac{1}{10}[/tex] to an improper fraction. Use this rule [tex]a\frac{b}{c} = \frac{ac + b}{c}[/tex].
[tex]\frac{44}{5} - \frac{50 * 10 + 1}{10}[/tex]
Step 5: Simplify 5 × 10 to 50.
[tex]\frac{44}{5} - \frac{50 + 1}{10}[/tex]
Step 6: Simplify 50 + 1 to 51.
[tex]\frac{44}{5} - \frac{51}{10}[/tex]
Step 7: Find the Least Common Denominator (LCD) of [tex]\frac{44}{5}, \frac{51}{10}[/tex]. In other words, find the Least Common Multiple (LCM) of 5, 10.
LCD = 10
Step 8: Make the denominators the same as the LCD.
[tex]\frac{44 * 2}{5 * 2} - \frac{51}{10}[/tex]
Step 9: Simplify. Denominators are now the same.
[tex]\frac{88}{10} - \frac{51}{10}[/tex]
Step 10: Join the denominators.
[tex]\frac{88- 51}{10}[/tex]
Step 11: Simplify.
[tex]\frac{37}{10}[/tex]
Step 12: Convert to a mixed fraction.

A carpet cleaner charges $59 for a service call and $30 for each room cleaned. A customer does not want to spend more than $125 for having the carpets in his house cleaned. Choose the correct inequality for the situation and the total number of rooms the customer can afford to have cleaned.
Answers
Answer:
[tex]59 + 30c \leq 125[/tex]
2 rooms
Step-by-step explanation:
Given
[tex]Base\ Amount = \$59[/tex]
[tex]Additional = \$30[/tex] per carpet
[tex]Customer\ Budget = \$125[/tex]
Required
Write an inequality to determine the situation
Represent the number of carpets with c
First, we need to determine an expression for the cleaner's charges:
This is:
[tex]59 + 30 * c[/tex]
[tex]59 + 30c[/tex]
Since the customer's budget do not exceed $125.
This implies that the cleaner's charges must be less than or equal to the budget.
So, we have:
[tex]59 + 30c \leq 125[/tex]
Solving further: [Collect Like Terms]
[tex]30c \leq 125 - 59\\[/tex]
[tex]30c \leq 66[/tex]
Divide through by 30
[tex]c \leq 66/30[/tex]
[tex]c \leq 2.2[/tex]
Since number of rooms can't be fraction;
The maximum number of rooms the customer can afford is 2
